Custom tracking domain

Improve your email deliverability by using your own domain or subdomain to track email events (opens, clicks) as well as handling unsubscribes.
When sending emails with Mailmeteor, you can keep your unique, brand-centric domain name to track emails openings and clicks. This makes sure your recipients trust links they click on your emails and highly improve your deliverability when tracking is ON.
Custom tracking domain is a Business feature
To use your own domain for tracking, you first need to upgrade on our Business plan.

Why should I use a custom tracking domain?

When tracking is ON, Mailmeteor uses by default a pool a domain names that are shared amongst all of our users. While this is standard practice, we consider it's the bare minimum that we can provide. So on top of a pool of domain names, each of our user has access to a unique, account-centric, subdomain to track events.
For example, for a user having the following email address [email protected], Mailmeteor will use the following unique subdomain to track emails.
While it makes our tracking service robust and reliable, we have learnt from experience that anti-spam filters may attribute a negative score to emails having a very long and/or low quality domain names in the email's content.
From the user's perspective, it makes totally sense. Someone is more likely to click on a link that starts with: instead of
That's why we recommend all our users that need reliable tracking metrics to configure a custom tracking domain. We even use our own tracking domain for our email communications.

  2. 3.
    In the "Custom tracking domain" section, click on "Configure".

    Enter the domain (or subdomain) you want to use. It should be a domain that you own and have write access to the DNS records.

    Add and save a new record with the inputs provided by us in the previous step.

Once your custom domain is saved, the dashboard will look as follow:

Which domain or subdomain should I use?

While technically, you can use any domain or subdomain that you own, we recommend using a short and tracking obvious subdomain of your primary domain.
For example, if your company uses for its public website, we recommend using as your custom tracking domain.
